GEORGE D. MACDOUGALL, OF BUFFALO, NEW YORK.

COKE-LORRY.

SPECIFICATION forming part of Letters Patent N 0. 748,390, dated December 29, 1903.

Application filed June 5, 1903. Serial No. 160,245- (No model.)

To all whom it may concern.-

Be it known that], GEORGE D. MACDOU- GALL,a citizen ofthe Dominion of Canada,and a resident of Buffalo, in the county of Erie and State of New York, have made a certain new and useful Invention in Ooke-Lorries; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure l is a side elevation of my invention as in application. Fig. 2 is a front view of the same, partially in section, on the line 2 2, Fig. 1. Fig. 3 is view similar to Fig. 1, on a smaller scale, and showing the coke-pan. Fig. 4L is a plan view of the invention.

The invention relates to horizontal openend coke-ovens; and it consists in the novel construction and combinations of parts, as hereinafter set forth. I

The object of the invention is, first, to provide means for preventing the coke from piling up on the platform'when it is pushed from the ovens, and, secondly, to avoid the necessity of shoveling up loose coke which may not enter the coke-pan.

In the accompanying drawings, illustrafing the invention, the letter a. designates a portion of the open end of a coke-oven, and b a trackway on the platform in front of the series of ovens. A transfer device or lorry is provided on the track, and it consists of a rectangular trough-shaped body a of about the same or a little greater width than the,

e have racks g resting thereupon and which are designed to he engaged by large pinions h upon the inner end portions of short shafts 71/, mounted in boxings upon side bars (1 of the truck-frame, said shafts having leverhandles Z at their outer ends. These side bars 01" have downward -arched transverse connections (1 within which fits the lower end portion of the trough c.

This laterally-adjustable lorry is designed to be moved along the platform-track, and the oven-door having been swung out of the way the lorry is placed directly opposite the open end of the oven, and the troughbody is moved, by means of the rack and pinion, toward the door until it strikes the door-frame. The width of the trough being but slightly greater than that of the oven, the coke will not collect in the trough as it is being drawn from the oven and pushed through the lorry into the coke-pan. Any residue that is left in the lorry after the operation of pushing the coke from one oven may remain until pushed out, when the charge from the next oven is drawn. The lateral adjustability of the trough body facilitates its movement along the face of the line of coke-ovens, as it can be moved transversely of the truck, so that it will readily pass by the buckstays or other projections, and when in position opposite the end of the oven to be discharged it can be moved up to close contact therewith and held in such contact while the charge is being drawn. The coke is therefore not liable to escape between the end of the trough-body on the sill of the oven-opening and pile up on the platform, and. as the transfer device is of bridge character, open at both ends, it can readily be kept in order as the-remains of a previous charge are pushed out by the-next charge.

Having described the invention; what I claim, and desire to secure by Letters Patent, 1s

1. In a coke-lorry, the combination of the truck having slideways,the trough open at both ends and having lateral flanges resting upon said slideways, a rack-bar upon one of said flanges, a boxing upon a side bar of said truck and carrying a shaft, a pinion upon the inner end of said shaft and engaging said rack-bar, and a lever-seat at the outer end,

IOC

connections thereof, the trough fitting within said downward-arched connections, and having intermediate lateral flanges resting upon said slideways and abutting against the in: ner walls thereof, a rack-bar upon one of said flanges, a boxing upon one of said side bars and carrying a shaft, a pinion upon the inner end of said shaft and engaging said rackbar, and a lever-seat at the outer end of said shaft, substantially as specified. 10

In testimony whereofI affix my signature in presence of two witnesses.
